MANUFACTURING METHOD OF RAMIE YARN WITH MONOFILAMENT SHAPE

摘要

PURPOSE: A monofilament type ramie raw yarn and a manufacturing method thereof are provided to prevent thread breakage and be applied to a mechanized weaving method. CONSTITUTION: A ramie raw yarn(12) is uniformly supplied to the inside of a hydrophilic polymer resin liquid tank through a separator of ramie raw yarn supply part(15). A ramie yarn is dip-coated with a hydrophilic polymer resin(18) inside a resin solution tank with a pick-up roller. A coating film of the hydrophilic polymer resin is formed using a heat-processing method with a drier. The hydrophilic polymer resin is polyvinyl alcohol or carboxymethylcellulose. The hydrophilic polymer resin weight compared to the ramie raw yarn is 60 or 80%.
